Surface Mount Fuses

Subminiature Surface Mount & Dip Types

FLAT-PAK

Slo-Blo

Fuse

203 Series

Fast-Acting and Slo-Blo

Fuse versions of the Flat-Pak Fuse designs are

available. Both designs are available in either a gull-wing surface mount

package or a DIP configuration for through-hole mounting.

These fuse designs feature a 250 VAC rating in a low profile,

rectangular package.
